Microbes used to make bioelectronic circuits

University of Wisconsin-Madison scientists have used single bacterial cells to make tiny bioelectronic circuits.

The bacteria, are guided, one at a time, down a channel to a pair of electrodes and become electrical “junctions,” allowing researchers to capture, interrogate and release bacterial cells one by one. Built into a sensor, such a capability would enable real-time detection of dangerous biological agents.
